我今天安装依赖包时一直报错

我之前把npm的registry换成国内的淘宝镜像的所以一开始认为报错跟链接什么的没什么关系。后来我在网上看了一下相关博客，都说换成cnpm就可以，我也尝试了一下，果然成功了。虽然我还不是特别理解这其中的奥妙之处，但是也得到了解决问题的方法。
下面三种方法都可以
1.通过config命令
npm config set registry http://registry.cnpmjs.org npm info underscore （如果上面配置正确这个命令会有字符串response）
2.命令行指定
npm --registry http://registry.cnpmjs.org info underscore
3.编辑 ~/.npmrc 加入下面内容
registry = http://registry.cnpmjs.org
结果
